IMPROVEMENT lN WATER-METERS.

Specification forming part of Letters Patent No. 126,974, dated May 21,1872.

Specification describing a new and Improved Water Meter, invented byEDWARD MARS- LAND, of Sing Sing, in the county of Westchester and Stateot New York.

Figure lis a top view of my improved Watermeter. Fig. 2 is averticalcentral section of the same on the line c c, Fig. 1. Fig. 3 is a' top.view ofthe discharge-chamber; and Fig. 4, a bottom view of therevolvingwheel.

Similar letters of reference indicate corresponding parts.

This invention relates to a new water-meter, in which the water isconveyed in spiral jets against the recessed edge of a wheel, revolvingthe same in exact ratio to the volume brought a-gainst it, and balancingit at the same time, to reduce friction. The invention consists,principally, in the respective arrangement of said wheel and the chamberwhence the water emanates, and also in the applicationl of projectingwings or fans to the wheel and case, for regulating the motion ofthesame and making it conform to the head of water.

A in the drawing represents the outer case ofthe meter, made ofcylindrical form, and receiving the Water at the bottom through a pipe,B, into a chamber, G. The entrance to the chamber C is protected by asieve, a, to keep impurities away from the meter. 1n a pipe, lv), thatprojects vertically from the center of the chamber (l, the water isconducted into a circular chamber, E, whose inclined or beveled ed gc bis perforated at Vregular intervals, the apertures d d being inclinedand oblique, as indicated in Figs. 2 and 3. Through these apertures thewater leaves the chamber E in spiral jets, which are propelled againstnotches or buckets e e formed in the overhanging annular liange fof awheel, F. The wheel F is mounted upon an axle, G, which is connectedwith the hollow shaft H of the recording mechanism l, said shaft H beingsuspended through the top ofthe case A, as shown. lhe shaft G is s0connected with H that it can slide up and down without affecting thelatter, but that its rotations will be, transmitted to H, and thence tothe gearing I, for being recorded. As the jets of water emanating fromthe chamber E strike the wheel F they cause it to revolve, and also liftit sufficiently from the seat or chamber E to reduce friction and tobalance it entirely on water. The upper surface ofthe Wheel F has aseries of projecting wings, g g, which, in passing through the waterthat fills the entire case A, retard the motion of the wheel. By meansof these wings g,.which may be made larger or smaller, at pleasure, themotion of the wheel can be regulated with exactness. There may also beprojecting ridges h h within the case A for similar purpose; but thesemay be omitted. The water, after hav-` ing turned the wheel F, iills thecaseA, and is finally discharged through a pipe, J, at the top of thecase. A

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The wheel F having ange f with notches e, combinedwith the chamber E having beveled edge b and oblique apertures d, as andfor the purpose described.

2. The wheel F having notches or buckets e e, and applied over thechamber E, to be revolved and supported by the jets of water that aredischarged from said chamber, as set forth.

3. The water-receiving case A, combined with wheel F having wings gprojecting into the water of said case, as and for the purposedescribed.

4. The combination of the case A, pipe B, and chambers O E with thewheel F, shaft G, and pipe J, all arranged substantially as herein shownand described.
